Test Apparatus for Cone Calorimeter Test

APPLICATION

:

This test is used to predict the performance of wall and ceiling linings as required by the Building Code of Australia.

PRINCIPLE

:

A 100mm x 100mm specimen is irradiated by a conical heater and the gasses evolved are ignited by a spark igniter. The products of combustion are collected by a flue and transported to an oxygen meter, which is used to assess the amount of oxygen used in the combustion process. From this plus other data collected by the apparatus, the Heat Release Rate of the product is calculated. The amount of smoke evolved in the testing is also measured.

SAMPLES REQUIRED FOR TESTING

:

Three specimens 100mm x 100mm by up to 50mm thick.

INTERPRETATION

:

The Australian Building Codes Board provides a spreadsheet calculator to convert the data from the Cone Calorimeter test to Time to Flashover Data as measured using the ISO 9705 Room Test. The class so calculated is then compared to the requirements set out in the Building Code of Australia.

SERVICE TARGET

:

10 working days.

COST

:
